The object of this invention is to provide a window construction and method of installing the same, whereby the window may be fitted and weather-stripped at the factory and shipped in knock-down form and assembled in a novel manner on the job. I

A further object is to provide a structure and method whereby the sash may ,be readily removed and replaced after once being installed in a building.

With the above and other equally important objects in view as will occur as the description progresses, reference will be had to the accompanying drawings forming a part of this speci- II fication and wherein:

Fig. 8 is an assembly view of the outer frame incorporated in a wall and showing the inner frame in juxtaposed position for assembly,

Figs. 9 and 10 are fragmentary detail views in elevation showing the method of applying the sash balances before closing the head opening in the inner frame, 7

Fig. 11 is a similar view showing the method 50 of applying and removing the upper parting stop sections in connection with the removal and insertion of the sash after the frame has been incorporated in the building.

Fig. 12 is a plan view of a fragment of a 55 bundle of sash,

Fig. 13 is an end view of a fragment of a bundle of side lambs, and

Fig. 14 is an end view of a fragment of a bundle of heads and sills.

In the drawings, reference numeral l designates the head, 2 the lambs, and 3 the sill of an inner window frame section. A parting stop 4 is provided in the head, and parting stop 5 is also provided in the side lambs, these being set into grooves B in the conventional manner. Upper and lower sash l and 8, respectively, are mounted in the inner window frame section at opposite sides of the parting stops, being previously fitted and weatherstripped at the factory. In shipping, several pairs of jambs will be packed separately as in Fig. 13, several pairs of heads and sills will be packed separately as in Fig. 14, and several pairs of sash will be bundled as in Fig. 12 or all parts for one or more complete windows may be packed in the same bundle.

In erecting the building, the outer frame parts H), II and I2, constituting the head, jambs and sill respectively of an outer frame are installed initially in the wall of the building around the Window opening as illustrated in Fig. 8, in accordance with the general idea of Patent 1,995,- 233 and thereafter at a later stage in the construction of the building, the inner frame parts i to 8 inclusive are assembled and installed, and the final trim ll, l5 and I6 applied according to the method set forth in said patent, the

' outer frame parts i0 and II and the trim parts i4, i5 and I6 providing outer stops for the sash.

The side portions of the side parting stops 5 (Fig. 7) that project from the grooves in the side jambs are rabbeted at H, and the inner corners of the sash l and 8 are also rabbeted as at [8. Weather strippings are applied to the parting stops and sash and located almost entirely within the rabbets thereof.

The jamb weather-stripping consists of a metal strip bent longitudinally to provide a central bridge portion 20, right-angular parallel sides 2i, right-angular aligned portions 22 parallel to the plane of the portion 20, and rightangular free side portions 24 parallel to the sides 2i. The portion 22 is applied to the exposed face of the parting strips 5, the portions 2i are applied to the sides of the parting strips 5, the portions 22 are applied to the bottoms of the rabbets I! in the plane of the inner face of the side jambs 2, and the portions 24 extend parallel with the portions 2i and form therewith and with the portions 22 a Ushaped channel A opening away from the side jamb.

The weather stripping for the sash each consists of a metal strip longitudinally bent to form lip 25 by which it is secured to the lamb side of the sash, a right-angular portion 26 that hugs the side of the rabbet I8, a right-angular portion 21 that parallels the plane of the portion 25 and that hugs the base of the rabbet I 8, and a right-angular free side portion 28 that extends parallel to portion 26 in the direction of the jamb, and forms with said portions 26 and 21 a channel 13 opening toward the side jamb. The bridge portion 20 and lips 25 are not countersunk.

After the building is plastered anddried and preferably after other rough work that could cause damage to sash runways has been completed, the bundled inner frame parts are delivered to the building. The two lambs 2 with their parting stops and Weatherstripping, factory applied, are then nailed to the sill 3. Both sash, I and 8, factory fitted, are then slid in from the top in proper interlocked engagement with the Weatherstripping. The sash balancing springs 30 are now, or were previously nailed at their upper ends 3| to the upper portion of the side jambs 2, their lower ends being arranged between the iambs and sash in conventional grooves therefor. The lower ends of the springs are equipped with plates 32 by means of which the springs may be wound to shorten and to place the desired tension upon the spring, whereupon, the plates 32 are nailed at 33 to the lower edge of the sash. The head i with its parting strip 4 and Weatherstripping is then nailed to the upper ends of the side jambs, as shown in Fig. 11, thereby completing the inner frame assembly. Obviously, all the parts may be painted or varnished before the parts are assembled.

Since all fitting and Weatherstripping was done at the factory, the assembled sash may now be operated as freely as after the inner frame unit is attached to the outer frame unit already in the wall.

In split frame construction according to said patent, the inner frame unit has no other stops than the parting stops or strip 4 and 5, that is to say, there are no customary outer stops. The inner frame unit with the sash in place may, nevertheless, be moved about without danger of the sash falling out since the interlocking Weatherstripping holds the sash in place without outer stops being present. This is a very desirable feature since it not only ofiers the added advantages of interlocking Weatherstripping but also permits the inner unit parts to be shipped knock-down making it unnecessary to ship the inner unit completely assembled as in the said patent.

After the inner frame unit has been incorporated in the building, the sash cannot be removed by merely reversing the steps employed in the original assembly of the frame, for obvious reasons, and other means must be provided for the removal and reincorporation of the sash. To permit this, the parting strips 5 on both sides of the window are divided into upper and lower sections, the joint C between the sections occurring at a point substantially midway between the upper and lower faces of the meeting rails of the sash when closed as shown in Fig. 3. In addition, there is provided a plowed recess 35 in each side jamb 2. The recess is in effect a deepening of the groove 5 of the side jamb in which the parting strips are seated, and does not extend entirely through the lamb.

To remove the sash, the same are. raised to their limit, with the meeting rails in the Fig. 4 position, and the screws 35 are thenremoved from the lower sections of the parting strips, 5, and the lower ends thereof pulled out of the groove 6 as shown in Fig. 5. Since, as seen in Figs. 4 and 6, the bottom rail of the lower sash,

when both sash are raised, is below the lower or lower edge of the raised upper sash which, for.

clarity, has been removed. As the lower section of parting strips on both sides of the window f-ulcrum upon the corner of the raised lower sash, their upper ends swing away from both sash, this being the direction of movement necessary to disengage the Weatherstripping of the parting strips from the Weatherstripping of the sash. When in the positions shown in Figs. 5 and 6, the parting strip sections are pulled longitudinally downward .into completely disassembled position.

One sash is then, if not previously, lowered to permit removal of the screws 36 of the upper sections of the parting strips 5. These sections are then slid downwardly in their grooves 6, and upon raising the sash to their full elevated positions, these upper parting strip sections may be slid entirely down to the permitted limit of movement and may then be removed in the same manner as the lower parting strip sections. This frees both sash except for the sash balancing springs which may be readily released when the sash are moved to a position permitting removal of the nails 3| or 32, as elected.

Obviously, by reversing the operation, the sash may be reassembled as in the original installation.
